I believe they are correct, but if you wish, I will double-check them for you. By correcting perspective in PS, you would end up with very little usable image width.īTW, I have not carefully checked my calculations. However, I think this is not what you're after. You could do that with a 16mm lens (16.18mm). If perspective is not an issue, then you need a 96 deg field of view with the camera 3m from the wall and the camera 1.6m off of the ground, in order to cover 9m of height. Remember you can use a smart phone app to trigger your camera via WiFi. If you can position the camera 25 cm from one wall, that would give you a 3.75m distance from the opposite wall, in which case your vertical coverage would be 11.25 m. Of course if you have your camera on a pole, you might back off somewhat further. The height you will be able to photograph will be 3*36/12 = 9m exactly. This will require no perspective correction. from atop a ladder or with the camera on a pole). If you are so inclined, you may shoot a building with a Sigma 12-24 (widest available rectilinear lens) at 12mm with the camera in a vertical orientation and the camera at a height of 4.5m (e.g. You could shoot a (hemi)spherical panorama with a fisheye lens and then create from it a cylindrical projection.Ī T/S 17 is simply not wide enough for a flat perspective, if that's what you're after. Is it possible to use this lens when the camera is on vertical orientation and shift it towards the top of the frame?Ģ) Could I use a Samyang 8mm fisheye and defish it? Would this destroy perspective? I am photographing buildings and I need accuracy on paralel and orthogonal lines.ģ) Do you suggest anything else? I can´t ask the people on the other side of the street to enter their houses to photograph the houses accross the street. Considering this, I would like to ask your opinions on lens choices:ġ) Would a tilt-shift lens help me in this project? I have never used a TS lens and I don´t know if I could overcome this by using a Canon TS-E 17mm and shifting it all the way towards the top of the frame. This would mean a 7mm lens, which does not exist. Considering that the camera on the tripod will be at 1,6m, I would need a lens with a 136 degrees horizontal field of view (considering that I would use a full frame camera - Canon EOS 6D, on vertical orientation). As I need some space to set the tripod and stand behind the camera to level it, compose, focus and shot, I think that I will be 3m away from the buildings. I want to make photographs of historical buildings which are 9 meters tall from a street which is only 4 meters wide. I am starting a photo project in a few months and I would like to hear your opinions about it.
